Use the PixInsight Blink process to inspect your result. Go into Batch Processing and load your BatchLinearFit image stack and the settings that you just saved. In ImPPG load your first BatchLinearFit image and tweak the curve and sharpening settings. All frames should have the same brightness. BatchLinearFit does a really good job smoothing out brightness variations in the image stack, which is very important for the next step of processing the stack in ImPPG. Use the PixInsight BatchLinearFit Script to normalize the TIF files created by AutoStakkert, specify tif for the Output extension. Click the Stack button and go do something else for a while until finished.
For Alignment Points select 200 and click place grid. For Image Size select remember so that all the file sizes are the same. For Stack Options select TIF, 25% frame stacking, no normalize or sharpening, select save in folders. Load all the SER files into AutoStakkert_3.1.4. 90 captures will just about fill a 64 gb thumb drive. Once framed, focused and tuned, I have Firecapture Autorun capture a series of 8 bit SER files, 100 frames with 60 second delay between. With this size ROI, the ASI294MM can output around 10 frames per second. The 2.3 um pixels match well with the 570mm focal length of the Lunt80 scope according to Marty’s spreadsheet. The full disk of the sun easily fits in a region of interest box of 2800x2800 pixels. In Bin 1 mode the ASI294mm can produce 47 megapixel images (8288x5644 pixels). Normally the ASI294MM produces 11.7 megapixel images (Bin 2 mode). Setup: Lunt 80THA DS on EQ6R mount with Hinode solar guider.įirecapture with ASI294MM camera using Bin 1 mode (2.3um pixels). Any feedback or suggestions for improvement would be appreciated. The following are my workflow notes that I have come up with for creating solar full disk animations.
